Michael Jackson’s This Is It was the No. 1 “Thriller” for movie audiences this Halloween.

The King of Pop’s highly anticipated musical documentary — comprised of This Is It Tour behind-the-scenes rehearsal footage — led the box office with $21.3 million in weekend ticket sales, knocking low-budget horror fest Paranormal Activity down to No. 2. This Is It has raised its five-day total worldwide to $101 million. Paranormal has raised $84.8 million total, according to The AP.
